Omega-3 Sources, Benefits and Effectiveness Every doctor suggests eating fatty fish twice or more in a week. The reason for such suggestion is that fish are rich in omega-3 fatty acids. These fats are healthy and promote health benefits including healthy heart, healthy skin, mental skills and several other health benefits. Our body can’t produce omega-3 fatty acids; we can only obtain it from our diet or supplements. Even it can be obtained from the diet sources but still most of the Americans do not get sufficient amount of omega-3. If you are one of them; you should start eating more fishes and other omega-3 foods. If you are not interested in changing your diet plan then simply take naturally formed omega-3 supplements.
